IOS Press SAT-Based Reachability Checking for Timed Automata with Discrete Data∗

Abstract. Reachability analysis for timed automata using SAT-based methods was considered in many papers, occurring to be a very efficient model checking technique. In this paper we show how to apply this method of verification to timed automata with discrete data, i.e., to standard timed automata augmented with integer variables. The theoretical description is supported by some pre-liminary experimental results. 1
